“日本zzzzz”西渝高铁康渝段日本zzzzz北屏隧道主洞掘进过半

  中新日本zzzzz网重庆12月14日电 (日本zzzzz记者 何蓬磊)记者14日从中铁十二局集团有限公司获悉,由该局承建的西渝高铁康渝段站前一标北屏隧道主洞掘进突破3800米,迎来了掘进过半的重要节点,为后续隧道贯通打下坚实基础。

  据悉,北屏隧道位于重庆市城口县境内,隧道全长7582米,最大埋深765米,为单洞双线隧道,分为进口、出口、斜井三个工作面。隧道穿越断层、岩堆、岩爆等诸多不良地质,并伴有瓦斯、天然气等多种有毒有害气体,施工安全风险高,技术难度大。

  据介绍,为应对复杂多变的地质条件,西渝高铁康渝段站前一标项目部采用动态施工方法,并配备防水板台车、多功能钻机、凿岩台车、仰拱液压栈桥等大型机械设备,有效保障了施工进度。同时,项目部还设立了人工钻爆隧道工序智能管理信息化系统,通过系统自动生成工序写实,并通过云计算分析循环用时、工序用时考核,实现了各工序的零搭接,有效提升了作业效率。

  值得一提的是,该项目部在施工中还充分践行绿色发展理念。通过实施雾暴除尘、清污分流等措施,在隧道口开展绿色建造,因地制宜打造“一洞一景”,与当地自然景观和谐融合。此外,项目部还积极引进先进的污水处理设备,以高水平生态环境保护支撑西渝高铁的高质量建设。

  西渝高铁是我国“八纵八横”高铁网北京至昆明的京昆通道和包头、银川至海口的包(银)海通道的重要组成部分。建成通车后,将与已建成运营的成都至重庆高铁、郑州至重庆高铁和在建的重庆至昆明高铁、西安至延安高铁等多条线路连通,推动中西部地区路网结构进一步完善,还将填补重庆城口县无铁路、无高铁的历史空白,极大便利沿线民众出行。(完)
